SAP HANA to ABAP encryption

344 Views

Hello to all the experts out there,

I have an problem understanding the network encryption from HANA to ABAP.

For Understanding:

ABAP - Client

HANA - Host

First: When we have an encrypted communication you'll always have two certificates, (server and client) that gets exchanged and need to be trusted.

But when I configure the SSL connection like in this guide: https://blogs.sap.com/2020/04/13/hana-secure-network-communication-part-ii/ until 7. Configure Clients, the Host will have a new certificate (import_own_cert). When I follow this guide, the Client also gets the same certificate to authenticate to the Host so no second certificate is needed?

Second: When I understand this correct, the Database Connection will be build from ABAP Side, but when the connection is build up, the Client fails, because it doesn't trust the certificate of the Host? Because the ABAP System is the client, doesn't have the Host to trust the Client and not the other way around?

Best Regards
